SPECIFICATION forming part of Letters Patent No. 464,862, dated December8, 1891.

Application filed February '7, 1891- Serial No. 380,589. (No model.)

To all whom it nmy concern:

Be it known that we, FRANK L. FONDA, ROBERT C. RoAoH, and WALTER H.UNDER- WOOD, all of Hutchinson, in the county of Reno and State ofKansas, have invented a new and Improved Ice-Machine, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a new and improved ice-machinewhich is simple and durable in construction, very effective inoperation, requiring a small amount of motive power for driving it, andpreventing leakage of the gas.

The invention consists of certain parts and details and combinations ofthe same, in which similar letters of reference indicate correspondingparts in all the figures.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the improvement, parts being insection. Fig. 2 is a sectional side elevation of the cylinder on theline 2 2 of Fig. 3. Fig. 3 is a transverse section of the same on theline 3 3 of Fig. '2. Fig. 4 is an enlarged sectional side elevation ofone of the cylinder-heads and the stuffingboxes. Fig. 5 is a perspectiveview of the spider for the cylinder. Fig. 6 is an enlarged sectionalside elevation of the suction-valve.

' Fig. 7 is a sectional plan view of the same on the line 7 7 of Fig. 6.Fig. 8 is an enlarged sectional side elevation of the dischargevalve.Fig. 9 is a sectional plan view of the same on the line 9 9 of Fig. 8.Fig. 1-0 is an enlarged side elevation of the cylindershaft and itswing, parts being in section; and Fig. 11 is an end elevation of thesame.

Theimproved ice-machine is provided with a cylinder A, formed with headsB B, having each a stufling-box O, in which is journaled thecylinder-shaft D, on which is secured within the cylinder A a radialwing E, serving to compress the gas. The outer ends of the shaft D aremounted to turn in suitable bearings and are provided with crank-arms D,connected by lin ks D with crank-arms D secured on a main driving-shaftD, receiving a rotary motion in any suitable manner, so

indicated in Figs. 3 and 5. '6 and 8, the suction-valve G opens inward,

as to impart an oscillating motion to the cylinder-shaft D and its wingE.

In the cylinderA is secured a spider F, formed with three radial arms FF F and two angular arms F and F extending from the arms F F to theinner surfaces of the cylinder A, as is plainly shown in Fig. 3. Each ofthe arms F F F F F is formed at its outer end with arflange F bolted orotherwise secured to the inner surface of the cylinder A to preventleakage in the cylinder. The several arms of the spider F extend fromone end of the cylinder to the other, so as to form longitudinalchambers A, A A A, and A of which the chamber A is thecompressing-chamber and extends between the arms F and F which arearranged at or nearly at right angles to each other. The wing Eoscillates in this chamber A, its sides moving close to the top surfacesof the arms F and F so as to fully expel all the contents of the chamberA. The chambers A and A are formed at the sides of the wing F and thesaid chambers are connected with each other by apertures F formed in thesaid wing F The chambers A and A thus forma single suction-chamber. Thechambers A and A are the discharge-chambers for the compressed fluid.The suction-chambers A and A are connected with the compressingchamber Aby suction-valves G, (see Figs. 3, 6, and 7,) secured in the arms F andF The discharge-chambers A and A are also connected with thecompressing-chamber A by the discharge-valves'H. (Shown in Figs. 3, 8,and 9.) The said valves G and H are located at opposite sides of thearms F and F and are secured in the arms F and F, as is plainly As shownin Figs.

while the discharge-valve H opens downward, the valves proper whenseated being flush with the top surfaces of the arms F and Frespectively.

In order to keep the compression-chamber A cool, a water-receptacle I isprovided, secured on top of the cylinder A and receiving itswater-supply through a pipe I, connected with a suitable source ofwater-supply. An overflow-pipe I also leads from the reservoir I tocarry off the surplus water, the pipes I and I being arranged inopposite ends of the reservoir I, as is plainly shown in Fig. 1.

Into one of the chambers A or A leads the fluid-inlet pipe J, providedwith the valve J for regulating the amount of fluid to be sucked intothe said chambers A and A From the discharge-chambers A and A lead thetwo pipes K and K, extending upward through the Water in the reservoirI, both connecting with a transversely-extending pipe K provided on oneend with a valve K for connecting or disconnecting the pipes K and KWith or from the pipe K From the latter extends upward a pipe K, whichdischarges into an oil-trap L, provided with a strainer or sieve L so asto divide the oiltrap into two compartments L and L of which the lowerone serves to catch the oil and is provided with a CllELW-Off cock Lwhile the upper one is connected with the end of a coil of pipe N,forming a condenser in connection With a spraying-tank N, having aperforated bottom and located over the said coil of pipe N. The otherend of the coil of the pipe N connects with a filter 0, having astrainer O and filled with a suitable filtering material to purify thefluid or freezing-mixture.

From the bottom of the filter 0 leads a pipe P, formed into a coilextending in the brinetank Q to cool the brine therein in the usualmanner. The pipe after leaving the tank Q leads to the suction-pipe J,to be returned to the compressor and used over again. The pipe K can bedirectly connected with the suction-pipe J by means of a pipe R,containing a valve R. A similar pipe R is formed to connect the pipe Kwith the suction-valve J, th'esaid pipe being also provided with a valveR The pipes K and K can also be con- 'nected with each other by a smallpipe R containing valves B In order to prevent leakage in the Wing E,the latter is provided with spring-pressed packing-strips E, projectingfrom the ends and pressed in contact with the heads B and the innersurface of the cylinder. One of these springpressed packing-strips isalso provided in the longitudinal groove formed in the spider at thejuncture of the arms F F to press against the inner edge of the wing orpiston E.

The stuffing-box 0 (shown in detail in Fig. 4) is provided with an oiler0, connected with an oil-pump to force a lubricant through the saidoiler and through apertures in the stuffing-box onto the cylinder-shaftD, so as to lubricate the latter.

The operation is as follows: \Vhen the several parts are in the positionshown in Figs. 1, 2, and 3 and the main driving-shaft D is rotated, thenan oscillating motion is given to the cylinder-shaft D, so that thewingE swings from one radial arm F or F to the other, and vice versa,thereby sucking in the fluid through the suction-valves G, compressingthe fluid on the return stroke, and finally discharging the compressedfluid through the discharge-valves H into the chambers A and A fromwhich the fluid passes through the pipes K K to the pipe K and from thelat ter to the pipe K into the oil-trap L. The fluid passes from theoil-trap L through the coil of pipe N of the condenser, and after beingcooled, passes through the filter 0 into the coil of pipe in the tank Q,there cooling the brine contained in the tank in the usual manner. Thesuction in the chambers A and A caused by the oscillating Wing E, drawsthe used gas from the coil of pipe in the tank Q back to the cylinder Ato be again compressed in the manner above described. Thus a continuousoperation is carried on,

the fluid being used over and over again. By

constructing the cylinder in the manner described the leakage usuallyoccurring in cylinders and reciprocating pistons is entirely avoided.The upper part of the cylinder A, containing the chamber A, is kept coolby the Water circulating in the reservoir I, W-hile'the lower part ofthe cylinder is cooled by the gas coming into the chambers A and A Th usthe chambers A and A are always full of gas, and a rush of thelatterthrough the suction-valves is avoided.

The valve within the cylinder Acanat any time be readily examined bysimply re'mov-in g one of the cylinder-heads B.

The construction of the entire machine is very durable and simple, andthe machine requires only a small amount of power for operating, thussaving considerable fuel. As the gas returned from the brine-tank Qpasses into the bottom chambers A and A no liquid ammonia is liable toflow into the compressing-chamber A. As the discharge-pipes K and K passthrough the water in the reservoir l, the temperature of the gas in thesaid pipes is reduced considerably previous to passing into the coil ofpipeN of the condenser, so that considerable water is saved in thelatter in cooling the coil of pipe M. As the wing E only oscillates, themachine can be run at a higher rate of speed than where the ordinarycylinder and a reciprocating .piston are used.

The system of pipes and valves R, R R R and R are used for pumping gasfrom the condenser N to the brine-tank Q. In order to do this, thevalves K on discharge-pipe K as Well as the valve J on the suction-pipeJ,

are closed and the valves R, R and R are opened successively. Themachine is now started in the ordinary manner, so thatallthe gas ispumped out of the condenser N. After this is accomplished the valves R,R and R are again closed to cut out the condenser for repairs or otherpurposes Without loss ofgas.

When it is desired to repair or perform otherwork on the machine, thenthevalves K are opened and valve J is keptshut, and as there is a vacuumin the condenser all or nearly all the gas will escape out of thecompressing-chambers and pass through pipes K, K, K and K to oil-trap Land from the latter to the condenser. The valves K are then closed. Thecompressor is now almost free of gas and can be conveniently examined orrepaired, the gas being mostly contained in the brine-tank pipes andcondenser.

Having thus described our invention, What we claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the cylinder A, having removable heads B,provided with aligned stuffing-boxes, and a spider F, extending from endto end of the cylinder and formed ofthree radial arms F F E, arm F beingapertured, and narrower arms F F along the under side of the arms F F,respectively, the outer edges of said arms being bolted to the cylinder,thus forming a compression-chamber A, connected inlet-chambers A A andseparate outlet-chambers A A a supply-pipe leading into saidinlet-chambers, spring-seated valves opening from chambers A A into thecompression-chamber, and outlet-valves opening from opposite sides ofchamber A into the respective chambers A A of the rocking shaftextending through the compression-chamber and stuffing-boxes, and apiston or Wing E, mounted on the shaft with its ends and longitudinaledges in close contact with the walls of said chamber, substantially asset forth.
